The Reliability Update (v1.2.0)

Building on v1.1.0, this release fixes problems found in a review of the whole application: transfers that could lose or damage data, how SSH host keys are trusted and saved, and many FTP and WebDAV edge cases. It also adds signed updates for macOS and AppImage, lets FTPS and WebDAV keep checking the server's key when certificate verification is off, and makes large queues, local operations and folder comparisons lighter on the interface.

3 new features, 67 fixes and 14 performance improvements, mostly in Transfers, SSH, SFTP and SCP and FTP, FTPS and WebDAV.

What's new
